When I start Jaspersoft Studio, most of the reports in my workspace are showing an error marker in the Project Explorer. In the problems view I see error descriptions which can't be true, such as that a variable called "CURRENT_PAGE" would be missing (as shown in screenshot). But such a variable isn't used anywhere in the source xml. Other reports are showing different errors (but also false ones).
The report can be previewed without any problems. In that case the error marker also disappears (or when I cleanup the project or rebuild the report).
But the annoying thing is that this error comes back every time I restart the studio and it is happening in almost every project and most of the reports!
